TECHNICAL FIELD

The field generally relates to systems and methods for using biometrics to predict and select music preferences and, in particular, systems and methods for using biometrics to predict and select music preferences for a vehicle occupant.

BACKGROUND

When listening to music, such as while driving in a car or at work, users often change to a different radio station or song if a musical selection does not appeal to them. Known systems, such as PANDORA, RHAPSODY and LAST.FM attempt to organize or utilize users' music preferences based on, for example, artists, reviews, and songs in users' libraries. With these known systems, explicit information and feedback from the users in the form of, for example, selection of preferred artists and songs, and purchase of songs, is required to develop and work with users' preferences and improve the listening experience.

Other known systems access a user's electronic collection of audio or video recordings to determine an audio/video preference profile for a user, and/or receive preference information from a user and adapt at least a portion of the preference information into at least one theme.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Exemplary embodiments of the invention will now be discussed in further detail with regard to systems and methods for using biometrics to select music preferences and, in particular, systems and methods for using biometrics to select music preferences for a vehicle occupant. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Users behave differently when they like or dislike a musical selection, such as a song, and this behavior can be quantitatively measured through different biometric measurements. Biometric measurements measure, for example, physiological and behavioral characteristics including, but not limited to, an individual's voice, movements, gestures, expressions, posture, etc.

Embodiments of the present invention use biometric information to determine when a user likes or dislikes a musical selection. As a result, music can be automatically adjusted based on the user's behavior and mood.

For example, according to an embodiment, when in a vehicle, such as a car, bus, truck, boat, airplane, etc., a song selection module (e.g., 105 in FIG. 1) can use information such as movements on the vehicle seats, pressure, temperature and humidity levels on the steering wheel or armrests, facial expressions, gestures, etc., to determine whether a user, such as the driver or a passenger in the vehicle, likes or dislikes musical selections. Users tend to provide implicit physical feedbacks when they like something, and these feedbacks can be measured using biometric sensors. Such feedbacks include, but are not limited to shaking one's body with the beat of the music and tapping a steering wheel when a user/driver likes a song.

Various biometric sensors are placed around the user(s) to measure quantities including, but not limited to, voice level, pulse rate, hand temperature, facial expressions (e.g., happy/sad) and body movements, including, but not limited to, tapping one's hands or feet, snapping fingers and bobbing one's head. Sensors may include, but are not limited to, pressure, motion, pulse rate and/or temperature sensors, located, for example, on the steering wheel, seat and/or any other surface in the vehicle, microphones and video and/or still image cameras located, for example, in or on the dashboard, visor, rearview mirror, window, radio and/or at a user's feet.

According to an embodiment, an initial training phase begins where the system learns what musical selections a user likes and dislikes under various biometric measurements, by using, for example, a machine learning algorithm. In accordance with an embodiment of the present invention, data concerning what a user likes and dislikes can be input to a machine learning algorithm as labels and processed using pattern recognition techniques. Like what is shown in FIG. 3, the data analyzed according to the machine learning algorithm during the initial training phase may include, but is not limited to, data from one or more sensors, cameras and microphones, previously analyzed or categorized data results, the current music/song stream and environment data. In accordance with an embodiment of the present invention, models and history data for analysis by a statistical filter 300 can be developed during the initial training phase.

According to an embodiment, once learning is completed, the system continuously measures biometric data from the user to determine what musical selections to play. For example, if the system detects the listener(s) are unhappy with the current selection, the system will note the data, and try to find a better song to play. In another example, if a user starts dancing in place to a certain song, the system will note the user's activity and update its models and history data that can be input into a statistical filter 300. In accordance with an embodiment, if the system puts on a musical selection that it has determined that a user will like, and a user changes or cancels the musical selection selected by the system, the system can recognize that a potential mistake has been made, as indicated by the user changing the song. The machine learning algorithm then updates its parameters with new information as to what biometric measurements indicate a wanted or unwanted musical selection.

According to an embodiment, in a modeling method for collecting and analyzing users' biometric information, reaction variant patterns are used to predict users' music preferences. Reaction variant patterns are variations in patterns detected from users, and are based on linear combinations of other patterns.

More specifically, according to an embodiment, there is an existing set of reaction patterns (for example, tap, nod, and jump) that have been already categorized with some preferred music labels/titles. These reaction patterns are denoted as a matrix H with columns that represent the patterns. When new patterns are detected, for example, dance movements, which are not categorized under any preferred labels/titles, the new patterns are denoted as y. Then, a sparse solution in x is determined according to the linear equation y=Hx to find out which labels/titles most overlap with nonzero entries in x, where x is a selector. In other words, the uncategorized reaction patterns are related to the closest categorized reaction patterns, and the uncategorized reaction patterns are then categorized under the same labels/titles as their closest categorized reaction patterns.

The patterns can include, but are not limited to, gestures, body measurements (pulse, humidity, face expressions, emotions, voice, etc.). According to an embodiment, a modality sensor in a vehicle can be used to detect variations in patterns. In an example, a dance movement pattern, including the combination of tapping of fingers and an excited voice, can be defined as a reaction variant pattern.

According to embodiments of the present invention, reaction variant patterns are used to build a prediction model that predicts if a user likes a song. Based on such a prediction, a song that is similar to the current preferences can be played. Referring to FIG. 3, these prediction models can be input into the statistical filter 300 for processing.

According to an embodiment of the present invention, the biometric information that is collected is not limited to the driver, and biometric information of one or more passengers inside the vehicle can be used to predict the music that will be liked in the vehicle. For example, the system can analyze the biometric information of multiple individuals to develop their preferences and search for any overlapping musical selections that would be liked by the group. It is to be understood, that the collection of the biometric information from the passengers can be performed in a same or similar matter as that of the driver.

According to an embodiment, the system is also capable of learning a song classification pattern, for example, based on artist or genre, from reading biometric data from the driver and/or passengers and relating the read data to one or more classification patterns. The system uses the song classification pattern or variable to choose songs from a song list and/or from scanning radio stations looking for preferred songs falling within the classification pattern.

In accordance with an embodiment, features other than biometric measurements, including, but not limited to environmental factors, such as the day of the week, time of day, weather, season and driving route, are factored into the learning algorithm when creating the personalized models. The environmental information can be gathered using, for example, a camera, a global positioning system (GPS), internal calendars and/or wireless networks.

The system can also detect conversations between occupants in the vehicle and lower the volume of a musical selection if it detects that the occupants in a vehicle are in a conversation mode, and bringing the volume back up as the conversation ceases.

The system can also be used outside of a vehicle, by, for example, bicycle riders (with portable music systems like iPods® or iPhones®) and in other situations when users are running, walking or sitting and listening their portable music systems. According to an embodiment, the system is capable of playing music that is already available on a portable music system, and can also search a frequency range, such as the FM range, to find songs that will match a user's preferences based on the biometric and other data.

Referring to FIG. 1, according to an embodiment of the present invention, the system 10 includes a vehicle 100, one or more users 101, a speaker 102, a musical selection scheduling controller 103, a database of musical selections 104 (e.g., songs and other music), a musical selection module 105, a camera 106, a microphone 107, other biometric sensors 108, a history database 109 including, for example, gestures, songs and other music, and an environmental input module 110, which gathers information on environmental factors, such as the day of the week, time of day, weather, season and driving route. The musical selection module 105 can be for example, a server, software, a processor, or any other module for performing the task of combining and analyzing the various factors and finding a musical selection to be played. The musical selection module can be located in the vehicle 100, or positioned remote from the vehicle 100, and accessed via a wireless network.

As can be seen in FIG. 1, the musical selection module 105 uses available data from a camera 106, microphone 107, other biometric sensors 108, a history database 109 of previously analyzed data of a user and/or the environment 110 to select, categorize and/or predict a musical selection that a user 101 likes. The musical selection module 105 can also take into account current or previously played music information from a scheduling controller 103, and draw music selections from a database 104 to be played via one or more speakers 102 in the vehicle 100. The musical selection module 105 also provides selected music data to the scheduling controller 103 for scheduling playing of a selection, to the database of musical selections 104 to update, for example, a song list, and to the history database 109 for future use and analysis. The scheduling controller 103 can be electrically coupled to a sound system in the vehicle 100 including speakers 102.

Referring to FIG. 2, according to an embodiment of the present invention, the musical selection module 105 includes, but is not limited to, an interpreter of biometric sensors 200, analyzer of gestures 201, an emotional classifier 202, a predictor of desirable musical selections for a user 203, and a system for searching for musical selections 204. According to an embodiment, the interpreter of biometric sensors 200, the analyzer of gestures 201, and the emotional classifier 202 interpret the data from any one of the camera 106, microphone 107 or other biometric sensors 108 to determine a mood and/or reaction of the user 101. These elements 200, 201 and 202 may use the historical data from database 109 to make the determination. Once the determination of mood and/or reaction of the user is made, the predictor of desirable musical selections 203 predicts songs and music that a user 101 will like and not like based on the determination, as well as information from databases 104 and 109. The system for searching 204 then searches for matching or similar songs in the database 104 or on FM frequencies. As stated above, according to an embodiment, the system 204 may search based on a song classification pattern, such as artist or genre.

In an embodiment, the interpreter of biometric sensors 200 is electrically coupled to the analyzer of gestures 201, and the analyzer of gestures is electrically coupled to the emotional classifier 202. With this configuration, the interpreter of biometric sensors 200 can send an input result (e.g., a conclusion as to a type of gesture made) to the analyzer of gestures 201, which can analyze a gesture to determine, for example, whether the gesture indicates satisfaction or dissatisfaction. The emotional classifier 202 can receive an input result from the analyzer of gestures 201, and classify an emotional state of the user as, for example, happy or sad. With the predictor of desirable musical selections 203 electrically coupled to the emotional classifier, the emotional classification can then be used to predict a desired musical selection based on the emotional classification. The system for searching 204, which is electrically coupled to the predictor 203, then searches for matching or similar songs in the database 104 or on FM frequencies based on the output of the predictor 203.

Referring to FIG. 3, the musical selection module includes a statistical filter 300. The statistical filter 300 receives input in the form of gesture models 302, emotional models 303, biometric data 304, history data 306, the current music/song stream 307 and environment data 308, and outputs a prediction of desirable musical selections 301 and other musical selection data 305, which may include, for example, undesirable songs. According to an embodiment, the models 302, 303 include the personalized models developed during the initial training phase, and from the reaction variant patterns as discussed above. In addition, the models 302, 303 can also include generalized models based on general human behavior. The history data 306 includes, for example, prior determinations of liked musical selections based on biometric and environmental data that has been previously collected and analyzed. The statistical filter 300 also takes into account present biometric and environmental data 304, 308, as well as the instant music stream 307.

Referring to FIG. 4, the statistical filter 300 uses one or more of the following pattern recognition tools: deep belief network 400, exemplar based methods 401, Gaussian mixture models 402, and conditional random fields 403. It is to be understood that the statistical filter is not limited to these pattern recognition tools, and other available probabilistic generative models, statistical modeling and/or probability functions may be used.

Referring to FIG. 5, a method for predicting and selecting music preferences according to an exemplary embodiment of the invention is shown. At block 500, the system monitors for sensory input. At block 501, a determination is made as to whether any inputs from the camera 106, microphone 107 or other biometric sensors 108 have been detected. If the answer is no at block 501, the system continues to monitor for sensory input. If the answer is yes at block 501, then the system queries whether a musical selection is being played at block 502. If the answer is no at block 502, the system continues to monitor for sensory input. If the answer is yes at block 502, then the system interprets the sensory input at block 503, and queries at block 504 whether the sensory input indicates satisfaction or happiness with the musical selection. If the answer is no at block 504, the system categorizes the musical selection as one which the user dislikes at block 505, finds a new musical selection which has previously been determined as liked by the user at block 506, and plays the new musical selection in place of the current musical selection at block 507, at which point, the method returns to block 500. If the answer is yes at block 504, the system categorizes the musical selection as one which the user likes at block 508, finds a new musical selection which has previously been determined as liked by the user and is similar to the current musical selection at block 509, and plays the new musical selection after the current musical selection has ended at block 510, at which point, the method returns to block 500. According to an embodiment, the environmental factors may also be factored into the analysis at, for example, at blocks 503 and 504.

The method of claim 1, further comprising playing the other music selection in place of the music selection being played if it is determined that the sensory input indicates dissatisfaction with the music selection being played, and the categorization of the music selection being played as one the user dislikes.
 3. The method of claim 1, further comprising playing the other music selection after the music selection being played ends in response to a determination that the sensory input indicates satisfaction with the music selection being played, and the categorization of the music selection being played as one the user likes.
 4. The method of claim 1, wherein the input from the biometric sensor comprises at least one of a pulse rate, a body temperature, a facial expression and a body movement.
 5. The method of claim 1, wherein the biometric sensor comprises at least one of a pressure sensor, a motion sensor, a pulse rate sensor, a temperature sensor and a camera.
 6. The method of claim 1, further comprising analyzing environmental data and selecting the other music selection based on the interpretation of the input from the biometric sensor and the environmental data.
 7. The method of claim 6, wherein the environmental data is at least one of a day of a week, a time of the day, weather, season and driving route.
 8. The method of claim 1, further comprising selecting the other music selection based on the interpretation of the input from the biometric sensor and previously analyzed biometric data.
 9. The method of claim 1, further comprising searching at least one of a database and FM frequencies for a matching or similar music selection to the other music selection.
 10. The method of claim 9, wherein the searching is performed according to a music classification pattern.
 11. The method of claim 1, further comprising analyzing models of biometric data applied on a filter, wherein the filter outputs a prediction of music selections for the user based on the models.
 12. The method of claim 11, wherein the models are developed from reaction variant patterns based on linear combinations of other patterns.
 13. The method of claim 11, wherein the models include personalized user models developed during a training phase.
 14. The method of claim 11, wherein the models are developed from reaction variant patterns, and the method further comprises: respectively categorizing existing reaction variant patterns under different music selections; detecting uncategorized reaction variant patterns; determining to which categorized reaction variant patterns the uncategorized reaction variant patterns are closest; and categorizing the uncategorized reaction variant patterns under the same music selections as their closest categorized reaction variant patterns.
 15. The method of claim 14, further comprising: denoting the existing reaction variant patterns as a matrix, wherein the determining to which categorized reaction variant patterns the uncategorized reaction variant patterns are closest comprises determining which music selections most overlap with nonzero entries when solving a linear equation based on the matrix.
 16. The method of claim 1, wherein the input from the biometric sensor comprises at least one of a facial expression and a body movement, and is captured by at least one of a motion sensor and a camera
 17. The method of claim 1, wherein: the vehicle includes another user; the input from the biometric sensor comprises biometric information of the user and the other user; and the method further comprises determining overlapping music selections liked by both the user and the other user.
 18. The method of claim 1, further comprising: detecting a conversation between the user and another occupant in the vehicle; decreasing a volume of the music selection being played based on the detection of the conversation; and increasing the volume of the music selection being played to a point prior to the decreasing upon detecting ceasing of the conversation.
